Pier site transfer problem

Hi all, Wanted to upgrade my aging (pre 1.1) pier installation. Downloaded the image running on the server and updated magritte and pier to their latest revisions on lr's repository. Then following http://www.lukas-renggli.ch/blog/export-import, I exported the current site contents. But when importing the resulting file back into the pier-1.2 one-click image , I get this error: Unable to import: 'Global "CZBibList" not found'. How do I fix this? Worst case, I can simply copy back the updated image but I'd like to use the new 1.2 one-click image as it is much smaller.
